What the FDA labels say
From the Flunisolide label · effective 2025-04-30
Persons who are on immunosuppressant doses of corticosteroids should be warned to avoid exposure to chickenpox or measles.
From the Fingolimod (Gilenya) label · effective 2026-07-22
In both cases, the patients were taking a 1.25 mg dose of fingolimod (higher than the recommended 0.5 mg dose) and had received high-dose corticosteroid therapy to treat suspected MS relapses.
Concomitant use of GILENYA with any of these therapies, and also with corticosteroids, would be expected to increase the risk of immunosuppression [see Drug Interactions (7.4)] .
Antineoplastic, Immunosuppressive, or Immune-Modulating Therapies Antineoplastic, immune-modulating, or immunosuppressive therapies, (including corticosteroids) are expected to increase the risk of immunosuppression, and the risk of additive immune system effects must be considered if these therapies are coadministered with GILENYA.
Prior and Concomitant Treatment with Antineoplastic, Immunosuppressive, or Immune-Modulating Therapies In clinical studies, patients who received GILENYA did not receive concomitant treatment with antineoplastic, non-corticosteroid immunosuppressive, or immune-modulating therapies used for treatment of MS.
